Problem with PhysX Lidar ROS2

Omniverse Isaac Sim

Hi
I have a problem with PhysX Lidar. When I use Carter, it works fine, but when I try to add PhysX Lidar to my own robot, it breaks. For instance, I can’t change the rotation of the Lidar, the laser scan isn’t appropriate. I use ROS2 Humble. What should I do? I will be really grateful for help.

I have the same Problem with the Kaya Robot! But I found nothing to solve it yet

Hi @dariusz.gogacz - Do you want to use PhysX lidar in ROS2 or are you ok with using RTX lidar w/ ROS2?

There’s a tutorial for RTX lidar w/ROS2 in Isaac Sim documentation.
https://docs.omniverse.nvidia.com/isaacsim/latest/ros2_tutorials/tutorial_ros2_rtx_lidar.html

Let us know.

What is the difference between the two ?

If it’s possible, I would like to use PhysX Lidar. As I mentioned, it works fine when I use sample robots.
